Question

In a competitive exam with 120 questions, there are three sections: General Knowledge (20 questions), Reasoning (50 questions), and Engish (50 questions). A candidate answered 70% of General knowledge 50% of Reasoning, and 30% of English questions correctly. If the minimum passing score is 60%, how many more questions did the candidate need to answer correctly to pass?

• A. 2
• B. 15
• C. 18
• D. 20

Answer 1

Answer:

C. 18

Total questions = 120

Passing score = 60% of 120

$0.60 \times 120 = 72$

So, the candidate needed 72 correct answers to pass.

Correct answers by section

• General Knowledge: (70%) of 20

$0.70 \times 20 = 14$

• Reasoning: (50%) of 50

$0.50 \times 50 = 25$

• English: (30%) of 50

$0.30 \times 50 = 15$

Total correct answers

14 + 25 + 15 = 54

Additional correct answers needed

72 - 54 = 18

Answer:

$\boxed{18}$

The candidate needed 18 more correct answers to pass.
